Application filed March 18, 1918. Serial N0. 222,998.

clothes pressing machine in which a stationy ary lower buck or platen supports the goods to be pressed, and a movable press head exerts the required pressure through an overhead transverse lever carrying said press head at a. forward end and connected at the rear end with the power mechanism, and the present improvement has for its object:

To provide a simple and efficient structural formation and association of parts whereby the pressing movement of the movable press head or platen of a clothes pressing machine is attained in an efficient, economical and convenient manner, all as will hereinafter more fully appear.

Figure '1, is an end elevation of an ordinary type of clothes pressing machine hav'- ing the present improvement applied.

Fig. 2, is a detail front elevation of the operating treadle and accessories of the controlling valve of the machine.

Like reference numerals indicate like parts in both views. i

Referring to the drawing, 1 designates the stationary platen or buck mounted in a raised position above the supporting stand 2 of the machine, and 3 designates the movof an overhead transverse lever 4 pivoted near its mid-length to the upper end of a I40 postor standard forming a part of the supportimg` stand 2 aforesaid.

6 designates a pin or stud carried on the rear ,end of the lever 4 aforesaid, for operative-engagement vwith the hereinafter described push bar forming a part of the power means of the machine.

7 designates a power cylinder mounted in a rearwardly inclined position on a similarly inclined supporting bracket 8 xedly attached to the rear portion ofthe supporting stand 2 aforesaid, and having a piston and piston rod 9, the upper end .of which has pivotal connection with the push bar above referred to, and as shown in Fig. 1.4

10 designates the push bar above referred to, and which is pivotally connected at its lower end to the piston rod 9 aforesaid, and formed near its upper end with a hook shape Ashoulder 1-1, adapted for engagement beneaththe pin or stud 6 aforesaid, -so` that when steam or like pressure is admitted into the lower end of the power cylinder 7, a powerful upward movement of said inter-engaged parts will take place, to in turn impart a like powerful downward movement 'to press head 3 and upon the garment or other article supported on the buck 1.

The purpose of the above described detachable connection between the push bar 10 and .the rockingframe 4, is to permit of an extended rocking movement lof said frame, `by hand, and which is found convenient and necessary in the attainment of the various operations of the machine in placing and replacing the goods or articles operated on. The short and powerful finaly downward movement of the press head 3 is attained by the power cylinder 7 which in the present structure has a comparativelyr short stroke, with a corresponding economy in the amount of steam required to operate the same.

12 designates a bell-crank lever fulcrumed to the pedestal of the platen 0r buck 1 and having link connection 13 with the aforesaid push bar 10 for effecting a Vconvenient disengagement of said push bar from its operative engagement with the rocking frame 4, when it is desired to effect by hand the above mentioned greater range of movement of said rocker fra-me 4 and associated press head 3.

14 designates-a spring by which the link connection 13 is connected with the post or standard 5 and tending to move the push bar 10 to its operative engagement with the yto an exhaust steam receiver, and with a pipe connection 18 to the power cylinder 7 aforesaid.

19 designates a rock lever .attached to the movable member or plug' of the controllingv valve 15 aforesaid, with its respective ends formed with stirrup recesses for convenient Y,

operation by the foot of the operator, to effect the three-fold operations of admitting steam' to the power cylinder 7, permitting an exhaust of steam from said cylinder, and

vention, what I claim es new and desire to secure 'by Letters latent, is

A clothes pressing machine comprising 'a supporting frame having a standard, a

supporting bracket at the rear portion of the supporting frame, a platen or buck having a pedestal and mounted on the supporting frame, a lever pvoted to the standard having a press-head at its forward end, a.

stud at its rear end, a, power cylinder mounted Qn the bracket'havng a piston and rod,

it l

and piyoted at its lower end to the piston y rod, a, bell-crank-lever fulcrumed to the ped' estal, a .link connection between the pushbar andthe bell-crank-lever, a, spring con-V necting the vstandard with the link vconnectionya,` Huid supply pipe connected with the power cylinder and a. controlling valve for the fluid sup 1y pipe.
